Abstract

The dependence of the Neel temperature on the thickness of the dysprosium layer has been studied. It is shown that the temperature range within which the paramagnetic–antiferromagnetic phase transition takes place depends on the microstructure and thickness of the dysprosium layer. Spin valves based on a CoFe alloy with dysprosium as an antiferromagnetic layer are manufactured via magnetron sputtering. It is shown that unidirectional anisotropy forms in the CoFe/Dy interface. The direction of the exchange bias field depends on the direction of the magnetic moment of the CoFe layer in the formation of exchange coupling.

在含有镝层的自旋阀中形成单向磁各向异性

摘要

已经研究了 Neel 温度对镝层厚度的依赖性。结果表明，顺磁-反铁磁相变发生的温度范围取决于镝层的微观结构和厚度。通过磁控溅射制造基于 CoFe 合金和镝作为反铁磁层的自旋阀。结果表明，在 CoFe/Dy 界面中形成了单向各向异性。交换偏置场的方向取决于形成交换耦合时CoFe层的磁矩方向。
